Benzonatate
Benzonatate is a non-opioid antitussive that reduces cough-receptor activity in the respiratory passages and lungs.
Key points
- Benzonatate has a local anaesthetic-like effect on cough receptors.
- Its capsule must remain intact because release in the mouth can numb the mouth and throat.
Tessalon connects the ingredient with cough in respiratory health. Here the capsule form materially affects safe identification: chewing or dissolving it can cause rapid oral numbness and choking risk, and accidental ingestion can be dangerous. The exact strength adds little beyond the rendered catalogue.
